For decades, finance has relied on paperwork, intermediaries, and manual processes. Today, programmable finance is changing the equation. Through smart contracts and blockchain technology, financial products can execute automatically, enforce rules transparently, and interact with other systems in real time. The future of finance isn't just digital. It's programmable. #ProgrammableFinance #Blockchain #Web3 #DeFi #SmartContracts #Fintech #DigitalAssets #BlockchainTechnology #FutureOfFinance #MkaitsTechnologies

Cover image for Most people trying to fix
Most people trying to fix a home appliance are stuck flipping through a PDF manual or guessing which part is causing an issue. OnSense set out to replace that with an app where entering a model number instantly surfaces specs, part breakdowns, and an AI assistant trained specifically on appliance repair knowledge — not a generic chatbot. What I worked on As part of the mobile engineering work on the React Native (Expo) app, I built the OCR module that lets users scan an appliance's nameplate with their camera to automatically identify the model and pull it into the system — removing the need to manually type in model numbers that are often worn, tiny, or hard to read. Stack: React Native (Expo) for iOS and Android OCR/camera-based scanning for nameplate recognition AI chat integration (OnSense GPT) for appliance-specific Q&A Backend integration with the platform's parts and repair-knowledge database What's in the app: Model lookup by number, with detailed specs and part breakdowns Exploded View module — an interactive, clickable diagram of appliance parts OnSense GPT chat assistant for error codes, repair steps, and part compatibility Nameplate scanning via OCR for fast, accurate model identification Parts cross-referencing against verified compatibility databases

Cover image for EarnDLT (GreenTruth) (https://earndlt.com) is a
EarnDLT (GreenTruth) (https://earndlt.com) is a blockchain-based carbon compliance platform that helps companies track and report emissions data under the EU's Carbon Border Adjustment Mechanism (CBAM) and Scope 3 supply-chain requirements. The backend was live and running on NestJS with a GraphQL API, but as the platform scaled, it needed to support third-party data providers who expected standard REST endpoints rather than a GraphQL schema. 🚀 What I worked on As part of the engineering team, I worked on migrating the core backend from GraphQL to a REST API architecture, on a platform already handling live compliance data. This involved mapping existing GraphQL queries and mutations to equivalent REST endpoints and reworking the data-access and request/response contracts so external providers could integrate cleanly. 🚀 Stack: NestJS for the backend framework TypeScript across the API surface PostgreSQL for compliance and emissions data Next.js on the frontend REST replacing GraphQL as the integration layer 🚀 The key challenge The migration ran over 1-2 months on a live platform handling real regulatory data, so downtime and inconsistency weren't options. The team took an incremental approach — standing up REST endpoints alongside the existing GraphQL layer, validating parity, then cutting over integrations gradually rather than in one hard switch. 🚀 What shipped A production REST API layer that opened EarnDLT up to third-party emissions-data providers, with no disruption to the platform's live CBAM/Scope 3 compliance reporting.

Cover image for Agent Evaluation Dashboard — Full-Stack
Agent Evaluation Dashboard — Full-Stack LLM Observability Tool Teams running AI agents in production need visibility into how those agents actually perform not just whether they respond, but how accurate, fast, and cost-efficient they are. I built a full-stack observability dashboard to solve exactly that: a single place to track accuracy, latency, API cost, and schema compliance across multiple LLM models and agent types. What I built A responsive Next.js (App Router) frontend styled with Tailwind CSS — deep purple sidebar, live accuracy/latency charts (Recharts), filterable eval-run tables, and per-model performance comparisons A Python FastAPI backend serving the dashboard's data layer, with token-based authentication protecting every route Full session handling: login, protected pages, automatic redirect for unauthenticated users A fully responsive layout collapsible drawer sidebar on mobile, reflowing grid on tablet/desktop

Cover image for DocMorph AI is a full-stack
DocMorph AI is a full-stack web application designed to eliminate manual data entry. It ingests locked, scanned PDFs, runs advanced Optical Character Recognition (OCR), and reconstructs the data into clean, editable Microsoft Word documents. The Challenge: Standard OCR scripts frequently fail or crash the server when attempting to process large, multi-page PDFs due to massive RAM consumption. The client needed a lightweight, scalable solution that wouldn't time out during heavy workloads. The Solution: I architected a decoupled monorepo system. The frontend was built with React for a seamless, drag-and-drop user experience. For the backend, I engineered a custom Node.js/Express.js server utilizing Tesseract.js. To ensure stability, I developed a custom text-chunking algorithm that slices the PDF into manageable data streams, processes them safely, and stitches the final layout together into a downloadable .docx file.

Cover image for Stop chasing leads by hand.
Stop chasing leads by hand. Let automation do it. Following up on emails takes a lot of time. You have to remember who you wrote to, who replied, and who needs a nudge. I built a tool that does this for you. Heres how it works: ✅ Put your contacts in a Google Sheet ✅ The first email goes out to everyone, with their name and company filled in ✅ If someone doesnt reply, it sends a follow-up on day 3, then day 8 (you choose the days) ✅ If someone replies, it stops right away ✅ All follow-ups land in the same email thread, so it looks natural ✅ It never sends on weekends You only talk to people who answer. The tool handles everyone else. What you get from me: 📦 The ready-to-use n8n workflow 📖 A simple step-by-step guide ⚙️ Setup help so it works with your Gmail and Google Sheet It works well for: Freelancers and agencies looking for clients Sales teams doing outreach Anyone who sends the same follow-ups again and again No expensive software. It runs on Gmail, Google Sheets, and n8n. 👉 Get it here: https://lnkd.in/dPHbfWKh (https://lnkd.in/dPHbfWKh)Please use it for real, relevant outreach and always give people a way to opt out. #automation (https://www.linkedin.com/search/results/all/?keywords=%23automation&origin=HASH_TAG_FROM_FEED) #n8n (https://www.linkedin.com/search/results/all/?keywords=%23n8n&origin=HASH_TAG_FROM_FEED) #emailmarketing (https://www.linkedin.com/search/results/all/?keywords=%23emailmarketing&origin=HASH_TAG_FROM_FEED) #leadgeneration (https://www.linkedin.com/search/results/all/?keywords=%23leadgeneration&origin=HASH_TAG_FROM_FEED) #freelance (https://www.linkedin.com/search/results/all/?keywords=%23freelance&origin=HASH_TAG_FROM_FEED)
